Bye Bye, Earth: Season 1

A giant squid-like monster enters and contaminates a lake, so the villagers request aid. Belle Lablac arrives, but the villagers fear her for her human looks. She slays the monster with her incredible strength and her sword Runding as it says it only wanted to return to the sea and spread its eggs. Belle drops an egg into the river and brings a tentacle back to her teacher Sian to eat. He advises her to take the test to become a Nomad so she can find where she belongs, as he has never seen creat

Belle reaches the field of rocks where she was supposedly born and befriends a seemingly mute rabbit boy. She goes to her hometown, Park City, and enters a tavern, remembering killing Sian. Some troublemakers attack the rabbit so Belle defends him, but finds that her sword becomes dull every time she tries to use it against a living being as part of Sian's curse. She beats them up regardless and is arrested. Losing patience, she breaks down the cell door and is bailed out by Sian's other student

Sian, who barely survived his duel with Belle, meets a woman about repairing his sword and they discuss how Belle is destined for great things. Belle defeats Kir Royale in their duel by breaking his flaming sword. The king accepts her and says her next test is to learn to turn her curse into a blessing. While she sleeps, the rabbit takes on a more humanoid form and finds the troublemakers from before plotting revenge on Belle; he makes them hallucinate being on fire. The next day, Gaff warns Bel

Belle is rewarded for defeating the slavers. Gaff tells her about two other knights, the shapeshifting mermaid Tiziano, and Adonis. Gaff breaks up a fight between Adonis and some knights who hate him for his habit of looting weapons from corpses. Belle takes a liking to some kitten-like creatures, but the next day, she finds some knights killed them and beat up Adonis for defending them. Enraged, Belle beats them up. Adonis says he heard Sian call Belle the Girl of Reason, but they do not know w

The army is attacked by giant spiders, making everyone panic and scatter. Belle is forced to defend a soldier named Benedictine when she panics after her boyfriend Gordon is killed and rises as a zombie. Kitty arrives and helps Belle defeat the zombie Gordon, and she learns Runding can cut zombies. They regroup with others and Adonis and find Tiziano raising the dead as zombies. She spots them and has the zombies attack, but the Underdogs from earlier lead them to a hiding place. The slavers exp

Kitty makes walls of fire to stave off the zombies, but they counter with water magic. Benedictine loses an eye and makes Belle go berserk, but Benedictine awakens the male soul living alongside hers from within - her body turning into a man's in the process - and calmly uses ice magic. Belle learns that Adonis uses so many swords because any sword he wields quickly degrades due to a curse. To lure Tiziano out, the group makes their stand in a graveyard. Kitty firebombs the zombies, then Tiziano

After the battle, they fight duels to honor the dead, but Belle goes home when she learns Gaff killed Adonis' father. Belle meets a sheltered girl named Sherry who seems to not know how to do anything. They take shelter from the rain in Benedictine, now Bennett's house, but Belle has to help bathe her. Belle learns Sherry is the princess. Sherry thanks her with a beautiful song, and Belle comments that singing takes a toll on her, just as Gaff comes to take Sherry home. Adonis reforges Kir Royal

Sherry invites Belle and her friends to a ball where she performs a song with new confidence. Belle dances with Kitty, who calls her "empty" as in free from obligations. Gaff confesses to Adonis that he killed his father and offers his father's sword if he will give up his collection, but Adonis challenges him to a duel instead. Kir Royale, who has become possessed and his arm is fused to his sword like Tiziano was, attacks them and then attacks the ball seeking revenge on Belle. Sherry is brief

The king says the final test to become a Nomad is simply to play a piano from the heart. Belle has never heard of pianos, but when she presses a key, it makes a resonating note. When she tries again, she is weighed down by doubt and loneliness and the piano makes no sound, so she fails the test, but she says she will never give up and will try again soon. Adonis is attacked by thugs and kills them. It is his turn to take the test, but when Belle leaves, he attacks the guards while demanding the

Adonis wakes up in a void and is greeted by a woman named Dram who forged Runding. She gives him a sword called Rusty Nail that can change shape and repair itself and does not deteriorate at his touch, then has Sian train him. Belle is still traumatized after almost being raped. When she joins a battle, she is sluggish and gets wounded, so Bennett and Guinness treat her in their room. Sian and Dram tell Adonis that Sian is actually Prince Fatale, son of the king, but abandoned his duties. Dram w
